Verdict

The call

The clearest difference is ads: Grok AI at none against ChatGPT's shown. Grok AI also leads on update cadence (every 2 days vs weekly). ChatGPT's advantage is ratings volume (11M vs 1.4M) and chart position (#1 vs #4). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. ChatGPT sells 8 in-app purchases, starting at $8.00 per month and Grok AI sells 12 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.8 for ChatGPT against 4.9 for Grok AI. That said, the two scores are not equally well evidenced: ChatGPT has 11M ratings behind it against 1.4M, so its average is the more settled of the two. Written reviews split almost evenly too, at 70% and 71% positive.
